Improving air quality is
a smart city priority
The Bettair platform permits cities
to map air pollution on a previously unimaginable scale
Live and breathe better in
your city, your home!


This novel smart city technology provides a highly efficient and
large-scale pollution-mapping tool for big cities. It provides them with the insights
and information they need to better understand and mitigate pollution.

The Platform

The platform is based on portable or fixed nodes which incorporate low cost gas sensors and are scalable, flexible and adaptable to any city.

Advanced Data Post-processing

Disruptive technology based on accurate low-cost gas sensors using advanced data post-processing techniques provides almost the same accuracy as traditional and more expensive equipment for a fraction of the price, thus allowing for the deployment of a large-scale and dense sensor grid.
Impressive Pearson Correlation higher than 0.8 compared to traditional AQM equipment

Custom Visualization Tools

The Air Quality Index (AQI) is calculated using the pollution data collected and presented with the latest GIS visualization tools, all of which is adaptable to the requirements of each city.

How does pollution affect you?

Air pollution is a major problem for public health. Outdoor air pollution
kills 3.3 million people every year, mostly in cities. The problem is
magnifying with the unpredecendent population growth in cities.

Bettair and the Environment

Bettair takes a complete product life cycle approach to
determining our environmental impact

Bettair’s life cycle analysis accounts for all emissions associated with
our products. Including manufacturing, packaging, transportation, and energy
consumed during use and recycling.
